Which radars cover Harrison?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 57 miles south-southwest. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Harrison | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 57 mi south-southwest | 4,200 ft | Good — most storms and steady rain or snow show clearly |

| KENX Albany, NY | 127 mi north | 14,000 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
